Shouldn't be a problem. You're compensating for earlier fuel-circuit restrictions by opening up later passages so overall fueling is close to appropriate.

Once you get carbs completely clean and factory-fresh, you'll find 3-washers is too much and may bog bike down when opening throttle. So you'll want to go down to 1-washer to adjust for muffler & snorkel-removal in mid-range.

In high-end/full-throttle you'll still be too-rich @ 10:1 AFR, which can really only be adjusted with changing main-jets and needle-taper. The Dynojet kit does this by using smaller main-jets and needle with thicker tip (less taper) to lean out high-end. Remember that '60s hot-rod slogan...
